I wasn't particularly fond of Superman's powers being watered-down so much, but while I wouldn't want to see it in the comics, it definitely worked for the series. I absolutely loved Timm's version on most of the villains (especially Brainiac)

Overall, it's not my favorite of the Timm cartoons (that would still be the original BTAS by a long-shot, with JLU coming in second), but it's still a really solid show.
